Udinga ulwazi lokuhlola isekethe ehlanganisiwe yomshini wokupakisha konke kulapha

Ukuhlolwa kwesekethe ehlanganisiwe yomshini wokupakisha, okuyinhloko kufanele kube ukulinganisa amaphuzu okuhlola ayisihluthulelo. Indlela evamile ukusebenzisa ukuhlolwa kwensimbi yonke i-voltage yenyawo kanye nephini lokumelana nomhlabathi, i-voltage yokufaka neyokukhipha, ukusetshenziswa kwamandla kanye ne-waveform yokufaka/yokukhipha, kanye nokungafani kwemiphumela yokuhlolwa namapharamitha esekethe ehlanganisiwe ajwayelekile, kungahlulela ukuthi isekethe ehlanganisiwe ezohlolwa ijwayelekile.

ku umshini wokupakisha , ama-microprocessor e-integrated circuit asetshenziswa kakhulu, i-thick film integrated circuit kanye ne-switch power supply operational amplifier IC. Ake sihlaziye ngokuningiliziwe ngalokhu.

umshini wokupakisha ukuhlolwa kwesekethe okuhlanganisiwe kukhiye wamaphuzu okuhlola esekethe okuhlanganisiwe.

1. Isihluthulelo sephuzu lokuhlola isekethe elihlanganisiwe le-microprocessor

Isihluthulelo sephuzu lokuhlola isekethe elihlanganisiwe le-microprocessor ikakhulukazi uhlangothi lokunikezwa kwamandla lwe-VDD, i-RESET, i-RESET, i-crystal IN vibration signal input, i-Xor crystal vibration signal output end of the input, output, kanye nezinye izifunda.

isivivinyo esiku-inthanethi silinganisa iphuzu elibalulekile lokumelana kanye nenani le-voltage futhi esijwayelekile singahlulela ukuthi isekethe ehlanganisiwe ijwayelekile;

2. Isihluthulelo sephuzu lokuhlola i-IC yokunikezwa kwamandla okushintsha

Isihluthulelo sephuzu lokuhlola i-IC yokunikezwa kwamandla okushintsha ngokuyinhloko ukuphela kokufakwayo kokutholwa kwe-Vc, i-voltage, okokufaka kokutholwa kwamanje, okukhiphayo kwe-pulse, njll.

Isivivinyo se-inthanethi sasetshenziswa ukukala i-voltage yesekethe ehlanganisiwe kanye nokumelana kwephini ngayinye, bese siqhathaniswa nedatha evamile, njengomehluko omkhulu, kufanele futhi kuhlolwe ingxenye ehlobene, ingxenye inqunywa ngaphansi kwesimo esijwayelekile, ingahlulela ukuthi isekethe ehlanganisiwe yonakele. Ku-switch integrated circuit switch tube iyi-core component, i-film thick film integrated circuit ye-large power switch tube uma kungakuhle ukungabaza i-switch tube ingalinganiswa ngokushintsha i-tube c, b, e kakhulu phakathi kokumelana phambili nokuhlehla ekwahluleleni.

3. Indawo yokuhlola ye-IC ye-amplifier yokusebenza eyinhloko

Isihluthulelo sephuzu lokuhlola le-IC ye-amplifier yokusebenza ngokuyinhloko ukufaka kanye nokukhipha. Leli phuzu lenani le-voltage engaguquki liphakeme.

isivivinyo, i-voltage ye-multimeter kuya ku-dc, ilinganisa inani le-voltage yokukhipha phakathi kokuphela kokunikezwa kwamandla kanye nokuphela kokunikezwa kwamandla okungekuhle. Ngama-tweezers ensimbi ngesandla, ngokulandelana, uthinta ukuphela kokufaka okubili kwe-amplifier yokusebenza (Joyina isignali ye-jamming), bese ubuka isimo sokujikijela kwewashi, i-pointer evamile, ye-multimeter izoba nokujikijela okukhulu, njengokuthi i-pointer ayinyakazi, khona-ke i-amplifier yokusebenza yonakele. 4. Isivivinyo sephuzu lesekethe elihlanganisiwe lebhayisikili likagesi.

emshinini wokupakisha, isekethe nesekethe ehlanganisiwe ye-TL494 esetshenziswa kakhulu engu-555 time base. Ake sibheke amaphuzu abalulekile ezindlela ezithile zokuhlola (1) Ukunqunywa kwesekethe ehlanganisiwe ye-T494

ukuhlolwa kwesekethe ehlanganisiwe yomshini wokupakisha ukuze kunqunywe isekethe ehlanganisiwe i-T494 ngezinyathelo ezilandelayo.

1) Lungisa ithuluzi. Ukuhlolwa kwamasekethe ahlanganisiwe ukuze kukhethwe imisebenzi eminingi, njenge-multimeter yedijithali, amamodeli anohlobo olusebenzayo lwe-MY68 kanye ne-multimeter yedijithali yohlobo lwe-MS820.

Bangakwazi ukubona imvamisa ye-150 KHZ kanye ne-200 KHZ. Badinga futhi i-oscilloscope, i-resistable resistance wire winding, njll.

2) Ukulinganiswa kwemvamisa ye-Oscillation. I-multimeter yokuqala yesikulufo ibe ngu-200 KHZ, inhlolovo yokuqala izinga le-oscillation le-T494 (Kwezinye izifunda ezihlanganisiwe ezifana ne-200 hz, ingalungisa igiya), ukuze ikwazi ukucacisa ngokunembile. I-oscillation ye-T494 ngamafidi angu-5, nangu-6, ngakho-ke amapeni e-multimeter nakulezi zinyawo ezimbili, anganquma igagasi le-sawtooth. Ishaja kanye nesifunda sokulawula semvamisa ye-oscillation engu-20 ~ 80 kh, imiphumela yokunquma inenani elithile, i-oscillation yesifunda esihlanganisiwe ijwayelekile, inani le-resistance capacitance lilungile.

uma kungekho zimpawu zokunyakazisa, kufanele ahlole indawo yokuxhumana namapeni, izintambo, njll. Uma ukuhlolwa kabusha kusengaphansi kwesilinganiso sezinombolo sesekethe ehlanganisiwe, kunenkinga.

uma imvamisa ingavunyelwe, okutshela u-Rr noma u-Cr, isimo sokubona kufanele silungiswe noma sishintshwe.

3) Ukulinganisa isilinganiso somsebenzi. Uma ilungele i-oscilloscope, i-T494 izokhipha iphinikhodi 9, 10, ixhumanise isikhombimsebenzisi sokufaka se-oscillograph, bese iqhubekela phambili ku-9, 10 feet kanye nomthwalo olinganisiwe. Lapha kubalulekile ukuqaphela ukuthi akukho mthwalo olinganisiwe, isilinganiso somsebenzi asilona isilinganiso esinembile, siyaphambuka enanini lomklamo wokuqala. Qaphela i-oscilloscope 9, 10 feet yefomu lokukhipha, ngasikhathi sinye lungisa isilinganiso somsebenzi: ukulawula isici, lungisa isibambo esilawula isivinini, ngokujikeleza okungu-0; Ishaja, lungisa inani lokumelana kusuka ku-0 kuya ku-6 feet (I-capacitance C, ngasikhathi sinye lungisa) 。 Ngalesi sikhathi kusuka ku-oscilloscope kufanele ubone izinguquko zesilinganiso somsebenzi kusuka ku-zero kuya ku-100% ububanzi.

Isekethe ehlanganisiwe yomshini wokupakisha ijwayelekile noma cha ihlobene nokusebenza okuvamile komshini, ngakho-ke kubalulekile, ngithemba ukuthi lesi sihloko sokuhlolwa kwesekethe ehlanganisiwe yomshini wokupakisha sizokusiza.

Noma nini lapho kuphakama umbuzo womshini wokulinganisa isisindo, umuntu uthola igama elithi ''.

Ukuze uthole amathiphu engeziwe namasu ezixazululo ezisebenzayo zokulinganisa isisindo, thola ukukhetha kwakho ku-Smart Weighing And Packing Machine.
